hi, can anyone help. have had a double story side extension built, architects plans state "walls - white painted pebble dash render with waterproofer on Celcon solar 215 blocks with 27mm thermal board. cn71 insulated lintels over windows with insulated gyproc to reveals". Had this built 4 years ago, after 6 months discovered rain coming through on window cills and damaging plaster work, had all windows resealled, still happened. last dec had all 4 windows replaced, first bit of rain we had started leaking, ahhh!!!!
now after reading architects plans discover no insulated gyproc around reveals, reveals just plastered directly onto blocks. also wall wasnt pebbledashed, just smooth rendered with waterproofer, if we now have the reveals done as stated would this solve our damp problem?
